Description
A Digital Electromagnetic Calorimeter (DECAL) is a highly granular device, which counts the number of particles in a shower rather than the total energy deposited. The required ultra-high granularity (50x50μm2) can be achieved using radiation hard CMOS Monolithic Active Pixel Sensors (MAPS).
We will present simulated results for the optimisation of a DECAL at future colliders (ILC/CLIC/FCC-hh). Particular focus will be on single particle resolutions, the impact of pile-up at hadron colliders and its reduction, and reconstruction algorithms to extract the additional shower information available from such a highly segmented detector. We will also present an overview, and initial measurements, of a radiation hard MAPS designed for such a calorimeter.
